        public Site getNE()
        Get the north-east site.

      • getNW

        public Site getNW()
        Get the north-west site.

      • getSE

        public Site getSE()
        Get the south-east site.

      • getSW

        public Site getSW()
        Get the south-west site.

      • getN

        public Site getN()
        Get the north site.

      • getS

        public Site getS()
        Get the south site.

      • getE

        public Site getE()
        Get the east site.

      • getW

        public Site getW()
        Get the west site.

      • getFigure

        public Figure getFigure()
        Get the figure to which this geometry object is attached. Returns null if there isn't one.
        Specified by:
        getFigure in interface Geometry

      • getShape

        public java.awt.Shape getShape()
        Get the current shape that defines this geometry
        Specified by:
        getShape in interface Geometry

      • getBounds

        public java.awt.geom.Rectangle2D getBounds()
        Get the current rectangle that defines this geometry. This returns the same shape as getShape(), but as a Rectangle2D type.

      • setMinimumSize

        public void setMinimumSize​(double minimumSize)
        Set the minimum size of the rectangle. The default is 1.0.

      • setShape

        public void setShape​(java.awt.Shape shape)
        Set the shape that defines this geometry object. The shape must be a Rectangle2D, or an exception will be thrown.
        Specified by:
        setShape in interface Geometry

      • setBounds

        public void setBounds​(java.awt.geom.Rectangle2D rect)
        Set the rectangle that defines this geometry object. This is the same as setShape(), but does not need to perform the type check.

      • sites

        public java.util.Iterator sites()
        Return an iteration over the sites in this geometry object.

      • translate

        public void translate​(double x,
                      double y)
        Translate the geometry object
        Specified by:
        translate in interface Geometry
